Background. Kærgård Plantage is the largest and most complex contaminated site in Denmark.
From 1956 to 1973, a pharmaceutical manufacturing facility, with regulatory approval, discharged 280,000 m3 of wastewater containing approximately 60,000 tons of various salts, sulfa drugs (antibiotics), barbiturates, lithium, mercury, cyanides, aniline/pyridine and organic solvents (PCE, DCM, benzene, toluene, alcohols) to six pits situated on a plantation approximately 400 meters from the beach. Given the complex and highly concentrated mixture of contaminants, implementation of multiple or sequenced remediation technologies may be required to achieve cleanup goals.
Activities. Bench tests with soil and groundwater from the site were performed to evaluate the feasibility
